No doubt these are great for kiln use, but I gave them to my husband as a Fathers Day gift for popping popcorn. The high temperatures would so quickly and easily ruin traditional gloves. Now, after 10 years, we are finally going to replace these wonderful fire resistant gloves! Well worth the money. They don't last forever, yet close! BTW if Blick company still sells popcorn poppers, they are the best way to pop corn.
